Apple has posted a bunch of new iPad videos that guide you through key aspects of the device. The videos are a sight for sore eyes and we mean literally – the quality, crispness, and shininess of the footage is outstanding, quite possibly Apple’s best promotional stuff yet.

The videos will wet your appetite while providing a more detailed outlook of the iPad’s key features, including the iBooks app, web browsing with Safari, listening to music with the iPod app, creating presentations, spreadsheets, and documents with the iWork suite, and more. The videos weren’t available on Apple’s YouTube channel at press time.

Cupertino, California-based consumer electronics powerhouse sure knows how to get the press rolling. By releasing those guided tour videos six days ahead the launch, users have more information to make an informed purchasing decision. Apple is also guaranteed to dominate the headlines in the run-up to the launch because most bloggers and media outlets will be inspecting every pixel of every frame, searching for clues to the stuff we didn’t know before. Geek will be doing our share of pixel-hunting and will soon inform you of our findings.

When Apple’s marketing machine begins hyping up the product aggressively, it’s usually a tell-tale sign of an imminent launch. Apple is slated to unleash the iPad this coming Saturday, April 3, at its own retail stores and select Best Buy locations. Amazon and AT&T could also carry the device later in the game.

Early sales estimates range betwen 400,000 and one million units. Of course, we won’t find out about the exact metrics until Apple puts out a press release announcing one millionth iPad sold. Last week, Apple put the final piece of the puzzle in place with the completion of the iPad App Store. The company has begun accepting the iPad submissions while promoting the store via a new Facebook page.
